"It means they're not incinerated. They're there waiting for us to go get them."

The second body was found beside an opened equipment box, which had contained emergency equipment, away from where the first body was found, Mr Monk said.

Little detail was visible, but he was confident it was a man's body, he said.

He called for authorities to meet with families to discuss options for entering the mine.

"The families are more determined than ever. We need mines rescue, maybe police and Government to sit round the table with us. The families are getting quite hostile and angry that nothing's being done.

"We want them to sit round the round table. We want to know what else there is available to us."

Police Assistant Commissioner Grant Nicholls confirmed the shape from the borehole footage looked like a body.

But the image was poor quality and police would need to conduct two to three months of electronic enhancement to confirm the find, he said.

"That image, in the vicinity of the three boxes, shows something that could be a body or possibly a number of things."

Mr Nicholls said Pike River was still unsafe to enter and finding bodies inside did not change that.

"While clarification of the images may help the investigation it is our understanding that under present conditions the mine is unsafe to enter."
